Subject: net/octeontx: fix dangling pointer on init failure
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5ed5df8073c80d1af9ec8c89a8b2a5299463058d;p=dpdk.git

net/octeontx: fix dangling pointer on init failure

When octeontx_create() is cleaning up, it does not correctly set
the mac_addrs variable to NULL, which will lead to a double free.

Fixes: 9e399b88ce2f ("net/octeontx: fix memory leak of MAC address table")
